At Davos, Donald Trump stunned world leaders with a fiery address about NATO, Greenland and global security. He claimed the alliance once “loved” him — calling him “daddy” — until he pressed for Arctic turf. Trump joked about Greenland as a “big beautiful piece of ice” the U.S. should own for peace and protection, while ribbing allies from France to Canada. He mixed up Iceland and Greenland, sparred with NATO chiefs, and questioned whether Europe would defend America.
